What do you think "Fat Albert" was about? A kid and his friends and the antics they got into - so what if Albert was a little on the heavy side - kids come in all different sizes. The character still played sports and was active with his friends and they didn't seem to think of him as different. Who created it, you know, right? BTW, in 2004, there was even a movie - starting Kenan Thompson.
Speedy Gonzalas would be, by pretty much any measure, a hero - a smart one at that, outwitting that ole Cat. As my granddaughter would say today "He saved the day". Several hit songs were also based on the character.
Mr. Magoo - yes, he was small, old, rich and near-sighted. He got into some real messes for not wearing his glasses - not too much different than some people I know today - including me, except I am not exactly "wealthy".
Hong Kong Phooey - again another superhero, a dog that uses Chinese martial arts to fight crime - thus the name. He saved the day too.
I fail to see why any of these creation characters would be frowned upon today or any day. In fact, they would be my preference over some of the animated shows out today.
Perhaps it is all in what one brings to the viewing in heart and mind.
